The patent pending design of the Perfect Brownie™ Baking Pan bakes each piece separately so they are flakey and crispy on the outside, but rich and gooey on the inside. The non-stick divider is so slippery not even yummy marshmallow treats will stick! Great for holidays, anniversaries, birthdays or barbecues! Not just for Brownies...make fluffy cakes, awesome bar cookies or grandma's apple pie squares and so much more!
